Martin, F.W.
Seventeen accessions of a West African okra species were observed in Puerto Rico, and were hybridized with the common okra species, Abelmoschus esculentus. The accessions are larger plants than common okra, but with shorter internodes. They also differ in numerous morphological and physiological characteristics. Most are more daylength sensitive than common okra. The F1 hybrids of the two species are quite sterile, although in some cases a few germinable F2 seeds are produced. Back-crosses, on the other hand, are more fertile than the F1 hybrids, and fertility is almost complete in the BC2. Some evidence was found of cytoplasmic interaction with chromosomes in production of sterile BC hybrids, a possibly useful tool for future use. Meanwhile, the transfer of genes from the new species to common okra appears very feasible.
